Full textNew therapy modalities for the treatment of advanced prostate cancer based on peptide analogues are reviewed. It has been shown that gastrin releasing peptide receptors (GRPr) are overexpressed in various types of cancer cells including prostate and breast cancer. Bombesin is an analogue of the mammalian GRP that binds with high specificity and affinity to GRPr. Significant research efforts have been devoted to the design bombesin analogues labeled with 177Lu considering the excellent radiophysical properties and commercial availability of the radionuclide. The aim of this work was to study the labeling and the quality control of a bombesin analogues with Lu-177 using DOTA and DTPA as chelate group and an aminoacidic spacers Gly5 and study the stability and biodistribution properties in order to evaluate the potencial for clinical application. The studies showed that the bombesin analogs were labeled with 177Lu with high radiochemical yield and high specific activity. In vitro stability studies showed that DOTA-conjugated peptides were more stable than DTPA-conjugated, when stored under refrigeration or in human serum. The partition coefficient values showed that 177LuDOTA-PG5N was more lipophilic when compared with 177LuDOTA-PG5M but without influence on blood clearance and liver uptake. The DOTA-conjugated peptides presented low binding to plasma proteins, that contributes for fast blood clearance in vivo. Biodistribution studies of 177LuDOTA-PG5M and 177LuDOTA-PG5N, showed significant renal uptake, as a result of the urinary excretion and low bone uptake, that indicated the in vivo stability of the 177Lu-DOTA-complexes. The compound 177LuDOTA-PG5M showed higher uptake on pancreas and intestinses and these organs presents high density of BBN receptors. But the in vitro binding assays (PC-3 tumors cells) showed similar results for both compounds.

Full textO convento de Chelas, situa-se no Vale de Chelas na zona oriental de Lisboa. É uma das mais antigas casas monásticas da cidade, tendo sido testemunho de variadas ocupações e usos diferenciados que imprimiram um caráter mutante ao longo dos anos. Encontra-se atualmente ocupado pelo Arquivo Geral do Exército, que mantém preservadas as suas dependências conventuais e industriais. O grande estado de degradação do Convento e o panorama de abandono do meio urbano, cria uma janela de oportunidade para reflexão acerca da sua reabilitação e perspetiva futura. Insere-se na discussão da importância da preservação do património religioso e industrial que se encontra ao longo do Vale de Chelas. É nesse sentido que se procura entender o papel que o Convento de Chelas e a sua cerca terão no futuro do Vale e a dinâmica que podem imprimir na sua envolvente. Assim, o objetivo do trabalho passa por analisar o objeto de estudo num enquadramento mais alargado e profundo, recorrendo a uma metodologia baseada na experiência humana no lugar, incidindo na individualidade e especificidade do Convento. Este conjunto conventual apresenta uma forte pretensão de se manter como parte integrante da paisagem do Vale que merece ser preservada. É nesse sentido, que se apresenta aqui, a proposta para uma intervenção fundamentada por uma leitura fenomenológica, que visa restituir um futuro a este conjunto conventual.
ABSTRACT: The Convent of Chelas is situated in the Chelas Valley in eastern Lisbon. It is one of the oldest monastics housed of the city, it has witnessed numerous occupations and different uses that gave a changing character throughout the years. It is currently occupied by the General Archives of the Army, maintaining its convent and industrial premises. The great state of degradation of the convent and the panorama of neglection of the urban environment characterized by void and ruins, gives a window opportunity to reflect on its rehabilitation and future perspective. It is part of the discussion on the importance of the preservation of the religious and industrial heritage that exists along the Chelas Valley. This is how one tries to understand the role that the Convent of Chelas and its fence will have in the valley and the consequent dynamics that will print in its surrounding. Thus, the objective of the project is to analyse the object of study in a broader and deeper context, using a methodology base on human experience in site, with focus on the individuality and specificity of the Convent. The Convent complex present a strong will to remain an integral part of the valley landscape that deserves to be preserved. Therefore, it is presented here, the proposal for an intervention based on a phenomenological reading, which aims to restore the future of this Convent.

Synthetic chelates used in phytoextraction, barely degradate in soil and pose a risk owing metal leaching. Natural organic acids can be an alternative to synthetic chelates thanks to their rapid biodegrability. The study was carried out aiming at evaluating the performance of three synthetic chelators and two natural aliphatic acids in desorbing Pb from a soil contaminated through recycling of battery wastes. Additionally, effects of the amendments on the Pb leaching from soil were also studied. The work comprised two experiments: (1) Pb desorption from soil using the rates of 0, 2, 5, 10, 20 and 30 mmol kg-1 of citric acid and oxalic, EDTA, DTPA and NTA; (2) Pb leaching from soil columns by applying citric acid, oxalic, EDTA, and NTA onto soil at the 0, 10, and 20 mmol kg-1 concentrations. EDTA promoted the highest desorption and leaching, hence is not recommended for phytoextraction programs in the area. High desorption of Pb along with low leaching, qualifies NTA as a potential Pb phytoextraction enhancer for the metal in the field condition. Neither citric acid nor oxalic acid posed risk regarding Pb leaching. On the other hand, they seem little promising for enhancing Pb phytoextraction due to the lowmetal concentration in soil solution.
A baixa degrabilidade no solo de quelantes sintéticos usados para induzir a fitoextração pode significar elevado risco ambiental pela lixiviação de metais pesados. Agentes quelantes naturais, mais rapidamente degradados no solo, podem ser uma alternativa para os quelantes sintéticos. Os objetivos do trabalho foram avaliar a capacidade de cinco agentes quelantes sintéticos e dois naturais de cadeia alifática na dessorção de Pb, além do risco de lixiviação desse metal promovida pelos quelantes em solo contaminado pela deposição de escórias resultantes da reciclagem de baterias automotivas. O trabalho compreendeu dois experimentos: (1) dessorção utilizando as concentrações de 0, 2, 5, 10, 20 e 30 mmol kg-1 de ácido cítrico e oxálico, EDTA, DTPA e NTA; (2) lixiviação de Pb realizada em colunas de PVC com concentrações de 0, 10 e 20 mmol kg-1 de ácido cítrico e oxálico, EDTA e NTA. O uso do EDTA promoveu elevada dessorção e lixiviação de Pb, não sendo recomendado o uso para programa de fitoextração na área em estudo. A elevada dessorção de Pb, aliada a baixa lixiviação promovida pelo NTA, qualifica o quelante para programa de fitoextração de Pb na área a qual as amostras de solo foram coletadas. Os quelantes orgânicos não apresentaram riscos para a lixiviação de Pb nas concentrações estudadas, mas parecem pouco promissores para a fitoextração de chumbo devido a baixa dessorção do metal.
